with steam or other vapor which is to be condensed.

It is the object of my invention to provide jet condenser apparatusinwhich the actual submergence of the removal pump may be lessened andthereby reduce the height of the apparatus, without, however reducingthe efliciency of the operation of the removal pump; or with a givensubmergence I am enabled to increase the efliciency of the'removal pump.To this end I establish separate chambers within the jet condenser whichare sealed from each other during operation by the injection water, andremove air from the first chamber and increase its pressure and deliverit into the second chamber, whereby there exists upon the water thereinto be removed by the removal pump a higher pressure than customary andhigher than the vacuum maintained in the system; and from the secondchamber the air is removed and raised to atmospheric pressure or othersuitable pressure. 9

For an illustration of one ofv the various forms my invention may take,reference may be had to the accompanying drawing.

Referring to the drawing, J is the jet condenser body receiving steam orother vapor to be condensed through the opening E. The cooling water isadmitted through the opening W into the distributing chamber C, fromwhich it has egress through the nozzles or openings N arranged in acircular series.

Beneaththese nozzles is the dilfuser or cone D having disposed at itscenter the core member F so shaped and so positioned with respect to thediffuser D as to produce an annular nozzle or diffuser passage G inalinement withthe nozzles or openings N. At 7 lected in the bottom ofthe body J .1

'From the condensin chamber above the diffuser D is an outlet for air ornon-condensable gases which delivers to an air removing pump of anysuitable type, as for example, a steam operated ejectorA having thesteam nozzle R receiving steam through the steam inlet H. The pump orejector A,

tact with the jets of cooling water emitted from the nozzles or openingsN and is condensed, the combined condensate and cooling Water beingdelivered through the alined .annular diffuser passage G, completelyfilling the same and forming a seal between the upper and lowerchambers.

The water is collected in the bottom of the body J and is removed by thecentrifugal pump P. w The ejector A withdraws air or gas from the upperchamber, in which itisdesirable to maintain an absolute pressurexofhtwoinches or less, referred to .30 inch mercury barometer. The removed gasis raised in pressure and delivered into the lower or second chamber inwhich any suitable higher absolute pressure is maintained. "And thesecond ejector A withdraws the air or gas from the second chamber andr'aises' it to atmospheric pressure or any other desired pressure. Y

There is maintained in the second or lower chamber an absolute pressurehigherjthan customary in this type of apparatus ,i*and this excess ofpressure is exerted upon the upper surface of the water in the bottom'ofthe body J, with the result that while the actual water level may not bechanged, there 1s greater pressure exerted on the suction side of theimpeller I of the pump P, greatly assisting the pump P to remove the'collected water. t

The effect of this construction is "there- Patented Mar. 26, 1918s foreto cause the pump P to operate more efliciently with a givensubmergence; or the actual submergence may be reduced because of thisexcess of pressure in the lower or 5 second chamber, and there followsin such case the beneficial result of reducing the height of theapparatus.

Where a steam actuated ejector A is employed, the motive steam thereofis condensed in the lower chamber, the condensate mingling with thewatertherein, and the second pump A is required in such case to removeonly air, or gas or uncondensable vapors.

The combination in a jet condenser, of a condensingchamber and a water collecting chamber, a diffuser .forming a connectionbetween said chambers and maintaining them independent when conductingcooling water, and means for extracting elastic fluid from saidcondensing chamber and deliverin it at higher pressure into the elasticfluid above the liquid in said collecting cham-- her through a passageindependent of said 2.
